What is Email authentication?

It is an advanced method to authenticate your email sending domain so that it'll allow our servers to accept and send emails on your behalf. This makes a smooth flow of emails passing through anti-spam filters and validates that your email is genuine.

Ultimately, it checks the legitimacy of the sender and prevents the sender’s email to get landed in spam folder/ junk box.

Different methods of email authentication

SPF/ Sender ID -It is a simple procedure to specify the mail servers (in our case it is zcsend.net) allowed to send mails for this domain. This is done by publishing the text records in DNS settings. Learn more about SPF

DKIM/ Domain Key - It is the most advanced protocol and is widely used by mail service providers. It allows the sender to sign their email by using digital signature in the header. Learn more about DKIM
